MPR-e and MSS-1c User Manual 3DB19901EFAA Edition 01 161
The TMN In-Band interface dedicated to TMN is used to connect the MPR-e NE to the
LAN exchanging TMN information through a VLAN mixed with the user Ethernet traffic.
This interface has a local default IP address, and the operator can reconfigure this IP
address as a public address.
The IP address of the TMN In-Band interface can be equal to the local IP address (NE IP
address).
If the IP address is different from the NE IP address, the TMN In-Band subnet is different
from the NE logical subnet calculated by masking the NE IP address with the TMN In-Band
subnet mask.
The default address is 192.168.100.1.
The default subnet mask is 255.255.255.0 (/24).
The default TMN In-Band VLAN ID is 4080.
3.10.10 — SAR and MPR-e Single NE IP addresses
When MPR-e is used in Single NE mode with 7705 SAR, MPR-e does not have its own IP
address. Conversely, all MPR-e to 7705 SARs are reachable with any SAR IP addresses
(IPv4 only).
MPR-e management traffic is handled by SAR routing function like any other IP stream.
As a direct consequence, there is no longer a special channel carrying TMN that the MPR-
e can explicitly recognize by use of a VLAN ID. Management traffic back and forth from
the MPR-e follows the 7705 SAR QoS policy and profile.
3.10.11 — MSS-1c traffic profiles
Three kinds of traffic profiles have been identified:
• TDM2TDM (9500 MPR → 9500 MPR, internal to an MPR network)
• TDM2Eth (9500 MPR→ TDM to Ethernet)
• MPR-E: ETH2ETH (Ethernet to Ethernet)
• MPR-A: DATA (Ethernet to Ethernet)
The second profile meets MEF8 standard.
